Research of the seasonal dynamics of the zooplankton abundance was carried out during the two-year period from January 2005 to December 2006. The sampling took place in monthly intervals from five different sites from the surface to the bottom of the lake. Taking into concidertion the temperature and oxygen regime the division on the epilimnion and hipolimnion was found out. Significant numerous in the total abundance of the zooplankton accomplish taxa Daphnia sp., Bosmina sp. and Cyclops sp. Zooplankton is more abundant in the epilimnium, in the layer with more favourable temperature and oxygen regime comparing with hipolimnium. Presence of the zooplankton has been recorded in the lack of the oxygen in hipolimnium during summer months. After the elimination following the heavy rains, the hasty increase of the zooplankton numerous was recorded. Abundance of the zooplankton was higher was in shallow parts of the lake in the area of the mouth comparing the sites close the dam. This research has shown that the zooplankton was present in all parts of the lake during entire year, especially in the epilimnion that characterizes with the favourable temperature and oxygen conditions.
